eAs-PURIFIER.

Patented une i3, avra. serial No. 546,367.

To all whom it vmay concern.

Be it known that l, CLARENCE E. Srnniz, a citizen of the United States, residing at Hillsdale, in the county of Hillsdale and State of Michigan,haveinvented certain new and useful improvements in Gas-Purifiers; and l do hereby declare the follow-ing to be a full, clear, and exact description of. the invention, such as will enable others skilled in the art to which it appert ins to make and use the same.

My invention relates to gas puriders or filters for purifying acetylene gas.

This device may be used in connection with any generator but is especially s'itable to bo attached to the generator on ar' automobile or motor boat.

The objectof the invention is to lili 'fr and cool gas made in this manner and ttl-2 catch all the sediment produced by the diss jflution of the calcium carbid and water.

Another object is to prevent stoppage in the pipes conducting the gas from the gem erator tothe burners.

Further objects will become appa-remi;l from the following description.

The invention consists of a reccptac e adapted to be attached to a generator in any suitable manner and provided with inlet and outlet pipes, the former for connection with the generator', and the .latter for conducting the purified gas to the burners.

'lhe upper portion of' the receptacle or casing into which the outlet pipe enters is filled with a filtering' substance or material, preferably mineral. wool, cotton or cloth. The inlet pipe passes through said filtering material and terminates below it at about the center of the vacant lower portion .or compartment of the receptacle. rThe reason for having the inlet pipe pass through the filteringn material is that the'vapor is caused to condense more rapidly when this pipe is kept cool by having said filtering 'material or absorbent packed around it. Tl e colder said pipe can be' kept, the more water will condense and fall to the bottom7 thus leaving the gas freer from moisture.

The bottom ofthe "filter casing is curved internally in any vertical. section and the inlet pipe terminates above the center thereof, vWhenI the gas strikes the bottom, it is,

herefore, 'evenly distributed so that it rises at? all sides and'strikes 'the full under surface of the filtering material and the capacity and efiiciency of the purifier is thus `greatly increased.

,lhe cover of the casing is removable so that the liltering material' may be readily renewed. lt is also sometimes necessary to take oli the cover or cap quickly in order to relieve high pressure Said cover or cap is made concave on its under` face so that the gas will rotate with greater rapidity than if" it were flat.

The invention also consistsin the features of construction and combinations of parts hereinafter described and specified in the claims.

In the accompanying drawing: Figure l is a plan view of a vpurifier or filter constructed `in accordance with my invention, `the cover and filtering material being removed. Fig'. 2 is an elevation oit the purifier complete,and Fig'. is a central vertical section on the line fte-far of Fig. l.

Referring' more particularly t-o the drawing', l designates the casing of' the filter or purifier which may be made or" cast, spun or stamped metal and which .is generally cylindrical in form except that its lower closed end is rounded or spherical.

In Figs. l and 2, l have shown a clamp ing' band 2 by means of which the filter may be connected or attached to a `generator or to any suitable support. About midway of the casing', there is placed a-screeu 3 supported upon pins l projecting inwardly from the walls of' `said casing. 'lhe upper compartment formed by said screen is filled with the filtering' material 5. lhe upper end of the casing is closed by the removable cover or cap 6, preferably screw threaded thereon and provided with a wrench-surface 7. 'lhe upper concave surface 8 ci said cap is shown in Fig. A drain cock 9 is arranged at the bottom of the casing. rlho inlet pipe l0 enters through the side of the casing near the top thereof and extends horizontally through the filtering material to the center of said casing. At that point, it is bent downwardly and extends vertically to near thc middle of' the lower vacant compartment of' the casing. The out-let or distributin pipe ll also enters through the side of the casing near the top thereof' but terminates within the upper compartment which is filled with the absorbent material. lhe ter- 2 sesgos minal of said outlet pipe is preferably arranged above the inlet pipe, as illustrated in Fig. 3, and is embedded in or covered by the ltering or absorbent material.

It will be noted that when the cap is re moved, the screen 3, as well as 'the filtering material, may be easily taken out for clean- ,ing or other purposes. This can readily be .comes too full of condensed steam.

Iclaim: v Y

1.*A gas purifier comprising a cylindrical casing entirely open at its upper end and rounded atits bottom, liltering material arranged in the upper portion of said casing, a cover for the open end of the casing, the under surface of said cover being concave for the purpose specified, an outlet pipe terminating in a vert-ical portion arranged cen trally of the casing and adapted to deliver the gas upon the central lowest point onthe bottom so that said gas is evenly distributed at all sides and in rising strikes the full under suri'ace of the ilterng material, and an outlet pipe for discharging the from the casing after it has passed throng said filter-ing material.

2. A gas purifier comprising a cylindrical casing entirely open at its upper end, pinsf40 projecting inward about midwaypf .saidcasing, a screen supported on said pins sothat it is capable of being removed throu 1 htheV open upper end of the casing, filtering inaterial arranged above said screen, a remov 5 able cover tor the open end of said casing, an inlet pipe terminating below the screen,r and an outlet pipe ior discliargingiegas' from the casing after it has passed through 4 said filtering material.

3. A gas puri'lier comprising a cylindrical casing open at its upper end, a removable cover for said open end, an inlet pipe terminating in a vertical portion arranged centrally of the casing and extending down near to the bottom thereof, pins projecting inwardly about midway of said casing, a screen fitted around the vertical portion of said inlet pipe and supported on. said pins so that it is capable or" being removable through the open end of the casing without removing said pipe, iiltering material arranged above said screen, and an outlet pipe for discharging the gas trom thev casing after it has passed through said ltering material.
